On-board high-precision op-amp circuit, to do accurate sampling and appropriate compensation and other functions to signal

The module can measure AC current within 5A, corresponding output analog can be adjusted

Under ideal conditions, the input voltage VCC is 3-35V, according to the potentiometer (adjust the amplification ratio, amplification range 0-100 times) to adjust the required output voltage, but the output (OUT) of the maximum voltage does not exceed 1 / 2 VCC.

The output signal is the AC voltage signal, and the output signal voltage does not exceed the maximum 1 / 2VCC.
